Sundance: Cera Misses out on Mescaline Head Trip

PARK CITY, Utah (AP) - Michael Cera can tell you how to cook a cactus to extract its psychedelic mescaline. But he can't tell you what a mescaline head trip is like, even though he drank the concoction.

Cera and his cast mates of the Sundance Film Festival premiere "Crystal Fairy" boiled a cactus and drank the noxious brew to get a sense of what their characters were supposed to experience on a mescaline trip.

The film follows them on a road trip through the Chilean desert in search of the San Pedro cactus for its hallucinogenic effects.

For some reason, Cera and his co-stars were unaffected by the mescaline, so he doesn't have any mind-altering experiences to share. He can describe the taste, which he says is "acrid, earthy, terrible."
